Tungsten Trioxide May Enable Cobalt-Free Batteries To Achieve Mass Production At An Early Date

wallpapers Industry 2020-06-30

I believe many people are relatively new to cobalt-free batteries. It is an upgraded version of lithium iron phosphate batteries. Cobalt-free cells are deeply concerned by many battery companies at home and abroad because of their advantage, such as lower production costs and higher volumetric energy density. However, they still face many problems in production. The transition metal tungsten trioxide nanoparticles are viral in the field of energy storage because of their high specific gravity, good photoelectric effect and electrochromism.

It is reported that many researchers have begun to use tungsten trioxide nanoparticles to replace the cobalt element in ternary materials so that in addition to ensuring that the prepared products have higher general performance, it can also effectively ease the supply of cobalt resources—the problem.

Cobalt metal is a rare metal and one of the most expensive metal materials in automotive battery materials. Recently, due to the decline in the growth rate of cobalt metal production and the strong demand for 3C and new energy vehicles, the need for cobalt has overgrown. Many industry players believe that the cobalt price will have a continuous upward momentum in the next two years.

As one of the essential elements in the positive electrode material of power batteries, cobalt can not only stabilize the layer structure of the article but also improve the charge and discharge characteristics of the material. Therefore, when the ratio of nickel content to cobalt content in the ternary material is seriously out of balances, it is likely to cause the power battery to overheat and cause combustion. At this time, special techniques or new materials are needed to replace the cobalt element, thereby avoiding this risk.

Tungsten trioxide ultrafine particles are a kind of tungsten oxide, which has the characteristics of the significant chemical diffusion coefficient and specific surface area, high melting temperature and mechanical stability, so it is very suitable as a raw material for the preparation of positive electrode to reduce the lithium-ion in The damage to the equipment caused by the movement of the active substance means that the prepared product can have more robust structural stability. Besides, the storage space of the positive electrode material and the lithium-ion transport channel will be significantly optimized. If tungsten trioxide nanomaterials can be successfully applied in the field of cathode materials, it may enable mass production of cobalt-free batteries at an early date.
